HEEL.

Application filed March 29, 1919.

To all whom it may concern:

Be it known that I, HERBERT KNIGHT, a citizen of the United States of America, rcsiding at the borough ,of Manhattan, city of New York, county and State of New York, have invented a new and useful Improvement in Heels, of which the following is a specification.

The invention relates to a heel possessing certain resilient qualities, and it consists of a hollow metal structure, so constructed as to provide an elastic, or spring tread, and specifically consisting of exterior supporting walls of metal with means inherent therein and integral therewith of providing a vertical give and take as the weight is imposed or removed.

Referring to the accompanying drawing which forms a part of this specification Figure 1, represents a vertical section of my improved heel, showing it in position, attached to a shoe.

Fig. 2, is a cross section of same on line IIII Fig. 1.

Fig. 3, is a vertical section on the line III-III Fig. 1.

Fig. 4, is a vertical longitudinal section of a modified arrangement.

Fig. 5, is a cross section on the line VV Fig. 4.

Fig. 6, is a vertical section on the line VIVI Fig. 4.

In this drawing, A- represents the wall of my improved heel and B the top lift or base piece: The wall A which is continuous both laterally and vertically from the rand to the top lift constitutes the support ing member or structure and is formed of spring metal; that is to say, metal resilient in its nature; contracting when a load is imposed and expanding when the load is removed.

These actions are permitted by, and in fact they are the result of, not only the clastic nature of the metal, but, also by the fact that I provide, at a suitable point between the upper and lower part of the structure, an offset, or protruding member, C formed integrally with the wall A. The vertical give and take occurs in the zone indicated by the member C.

The olfset, or protuberance C subdivides the vertical wall into upper and lower sections; should there be any slight give in the Specification of Letters Patent.

walls A the collapsibility of the structure is mainly resident in this offset or lateral extension G. Under vertical pressure the give and take at C is relatively very much greater than in the vertical walls A: in fact, I prefor to have the walls A hold to their upright form and position.

The member C is in the nature of a bellows; the corners D and E approach and recede from one another as the weight upon the upper plate F is imposed, or removed. The quality and nature of the metal employed should be such as to give just the requisite amount of spring, or rebound in the bellows, to cushion the heel and eliminate the ar or blow to the wearer and which ordinarily attaches to the employment of hard heels, such as leather or wood.

It will be noted that the bellows G extends entirely around the periphery of the heel structure and that it is of equal dimension and equal cross-section throughout its entire extent. Being circumferential and of equal strength throughout, it provides a cushion of dependable value and etliciency. As constructed also, and as shown in the drawings, the hollow interior is entirely sealed from the exterior, thereby preventing dirt and dust from entering into the hollow heel; in fact, any hollow heel structure that permits the entrance and accumulation of dust from the outside is, from the standpoint of usage, entirely valueless.

It will be noted by referring to the drawings that the space included in and by the wall A, and the upper and lower )1 ate F, and B, is entirely free and clear: this con struction lends lightness to the heel.

Being made of metal also, the heel, as an article of manufacture and one which is intended for wide and general use, is very durable and possesses peculiar ecolwmic value in that respect.

At G I show turned over ends at the upper part and at H means of attaching the heel to the upper plate F, the latter being secured in and to the sole of the shoe J, in any suitable manner.

In the form shown in Figs. 1, 2 and 3, the upper ends G of the metal walls A are bent over and inwardly being folded at right angles to the vertical walls, and in this manner the top, side walls, and bottom plate are formed integrally; of one piece drawings, that the I integral structure including the offset part i In the form shown in Figs. 4, 5 and 6, the part G is bent inwardly; in the nar-' row heel the outwardly turned flange works to good advantage; in the wider heel, the inwardly turned flange is best.

Besides being superior to the ordinary leather. heel by reason of its resilient qualities, my present invention is preferable to such a heel, or to a rubber heel, in that it will notwear of}? at the edges but that it will ep it ar a d sh p atall tim I do. not laim a metal heel made of sec-. tions which telescope one over the other; e a ity Of siran ake as. the W g t is imposed or removed resides, in the case of my improved heel, in the metal itself; it is, as stated, a continuous heel structure a e he op be t ot om. nd ar un the entire circumference.

It will be seen, by referring to the cross sections Figs. 2 and 5, of the two different of metal, the

forms presented, that whereas the heel structure broadens out into the ordinary horse shoe shape at the bottom, the central or resilient zone is circular; such a structure gives a balanced and even movement, responsive to the duties expected and req d- I may provide on the upper and lower sections of the heel and exterior to, the metal supporting Walls A- fillers, K and L; these tillers serveto round out the structure give a finished shape and form to the heel; the fillers can be made of leather, wood, or any other suitable material.

It will be observed by referring to. the. filler. K-.,, extends from the upper edge of the heel down to the protuberance o1 ofiset C: and that the filler L, extends upwardly from the base of the. heel to but that neither of the fillers encroach upon the offset C nor do. they in any manner impair the freedom of the elastic movement of the offset; the compression and the rebound of the elastic offset is just the same as if the fillers were entirely absent.

Having thus described my invention, the following is what I claim as new and useful 4:. A hollow heel embodying supporting.

walls of metal, with an integrally formed circumferential bellows member, providing a cushion.

5. A hollow heel embodying metal supporting walls, with an integrally formed, partially collapsible, peripheral section.

6. A hollow heel embodying an upper and lower section providing metallic supporting walls, with a collapsible member. positioned intermediate of, and formed integrally with, said sections.

7. A hollow, heel embodying continuous vertical supporting walls of metal, with means, extending laterally from the walls and formed integrally therewith, for pro.- viding a spring tread.

8.. A hollow heel entirely sealed from the exterior embodying metal supporting Walls, with an integrally formed and relatively more resilient cushioning member.

9. A hollow heel embodying metal supporting walls, having a peripheral zone in: tegral therewith and of relative greater resiliency. I

10. A hollow heel embodying metal supporting walls, with a zone of relative greater resiliency, providing a uniformly distributed peripheral cushion.

11. A hollow heel embodying an upperand lower section providing metallic supporting walls, an integrally formed, and

outwardly extending bellows, and cxteriorly posltioncd fillers on the walls above and:

below the bellows.
